Introducing the iconic 1956 DKW RT 125 2, a motorcycle that captures the essence of post-war European sport biking. Born from the innovative spirit of the DKW brand, this lightweight two-stroke beauty was designed for the spirited rider seeking performance without sacrificing style. Positioned in the sport category, the RT 125 2 stands out with its elegant lines and practical engineering, making it not only a pleasure to ride but a sought-after collectible for vintage motorcycle enthusiasts. At the heart of the RT 125 2 lies a feisty single-cylinder, two-stroke engine boasting a displacement of 123cc. With a modest output of 5.7 horsepower at 5000 RPM, this motorcycle is all about agility rather than brute force, delivering a thrilling riding experience especially suited for urban environments and winding country roads. The lightweight construction, tipping the scales at just 86 kg (189.6 lbs), combined with a three-speed gearbox and a responsive wet multiplate clutch, allows for nimble handling and a fun, engaging ride.

The DKW RT 125 2 is not just about performance; it also features a host of technical highlights that enhance its riding experience. The single cradle frame ensures a sturdy yet lightweight structure, while the telescopic front fork provides a smooth ride over uneven terrain. With expanding drum brakes both front and rear, the RT 125 2 offers reliable stopping power, instilling confidence in the rider. Additionally, with a fuel capacity of 9.5 liters (2.51 gallons), this motorcycle promises an enjoyable ride with fewer stops at the pump. The kickstarter adds a touch of classic charm, transporting riders back to a simpler time when the thrill of the ride was paramount. **
